る。According to the external operation mechanism of the circuit breaker of claim 1, the external operation hand is provided around the external operation handle of the lid.
Since the wall that protrudes above the
There is no danger of hitting the
Become. Moreover, the lid and the external operation handle open the box.
Since it is closed, it is difficult for dust to enter the circuit breaker
It does not interfere with the operation of the various parts of the circuit breaker. Since the lid body has an openable / closable cover that covers the external operation handle, there is no risk of touching the external operation handle from the upper surface side of the lid body , and for example, even if a child throws a ball, it does not directly hit the external operation handle. Moreover, the risk of malfunction is reduced. Further, by sandwiching and fitting the substantially U-shaped elastic shaft across the back surface of the recess and the mounting hole,
The work of attaching the elastic shaft to the cover and the lid becomes easy.
